On June 15, the Environmental Protection Agency (EPA) gave final approval to move forward with the sale of E15 ethanol blends. The final issue preventing E15 from moving forward focused on residual fuel left in the hose of single hose pumps that would offer E15 and other fuels.
This announcement knocks down the lone, significant regulatory hurdle standing in the way of getting E15 in the marketplace for passenger vehicles 2001 and newer, according to a statement by the Renewable Fuels Association and Growth Energy. With guidance on that issue from the EPA, fuel providers and retailers wishing to sell E15 can do so provided they register with EPA and follow approved mis-fueling mitigation protocols.
EPA made the decision in response to a request by Growth Energy and 54 ethanol manufacturers. On October 13, 2010, EPA granted the first partial waver for E15 use in 2007 and newer light-duty motor vehicles (cars, light-duty trucks and medium-duty passenger vehicles).
On January 21, 2011, EPA granted the second partial waver for E15 in 2001-2006 light-duty motor vehicles. These decisions were based on test results provided by the U.S. Department of Energy and other test data and information regarding the potential effect of E15 on vehicle emissions.
